Yes, that's what a policeman was on paper when a couple of guys were deciding who would be the guy that saves your life when a delinquent tries to take it from you: uncorruptible, not interested in personal gain when on duty, not interested in the amount of respect he thinks he deserves, would indiscriminately arrest the president's son if he caught him snorting cocaine, would consider his gun the last resort (actually). Basically an omnipotent, indiscriminate, fair god would be a great policeman, not a regular human being. We have no cops; we only have egomaniacs, thugs and those who do their best at becoming that what they were learning for at the academy.
